Breadmaker Kneading Blade stuck on the Shaft

I just newly bought a breadmaker, and made my first loaf. It was beautiful and tasteful.

When the bread was done and I turned the bread pan upside down, the bread easily fell out, and the kneading blades was not coming out with it. I had understood, after reading some posts online, that one of the major challenges with using a breadmaker is how difficult to get the kneading blade out of the bread. Therefore, I was feeling lucky at that moment. However my positive feeling did not stay long, as I realised that I was unable to detach the kneading blade from the shaft at all...

Anyone has experienced the same problem? Shall I just return the product, as I ordered it from Amazon.
